A few comments about the UV proposals:

 > missing too.

C centres the view around the cursor in the 3d view, but there
is no cursor in the UV editor. 'View Selected' and 'View All'
were added in 2.37.

This is not going to happen. Not because it is a bad feature,
but because there is a technical  issue: datablocks are only
deleted on save/reload. I can't get around that.

I don't see how this is that useful, or even consistent with the
behaviour of the X key in other modes. X key deletes what
you have selected, this would only add confusion in my opinion.

Subsurf will be integrated much better. In fact, zr just committed
what you requested a few hours ago :).

There will be multiple uv coordinate channels. But attaching
them to an image would be a bad idea because images are
used also for other things than uv mapping, and you might
want to share uv coords for different textures/images.

Instead, there will probably be a list of uv channels for each

I don't get this one. The texture repeats by default already?
